The world enters the age of mythology.

In Lu Yiming's earphones, a group of people were discussing enthusiastically.

"They have a position called Celestial Master. From the analysis of spiritual strength, it has reached the limit of human beings. They should follow the results of Xuanwu's study."

"One quota actually costs 200 million, and 100 quotas are discounted by [-] million... It's really expensive, it's too expensive!"

"If it is really possible to let human beings reach their limits, the price of 200 million is not expensive, not at all. Our current A-level soldiers are only 20. Is it expensive to train one with 200 million? It is not expensive at all! It is even possible Said it was extremely cheap!"

"2 million is not expensive to train one!"

"With one hundred places, there may not be many people who can learn something in the end. Otherwise, the number of powerful fighters in this giant tortoise civilization will not be so few. If only a few of the 100 people succeed, I think it is still relatively expensive in terms of conversion. .”

After all, the capital of the sea of ​​clouds only relies on human beings to create a GDP of only 600 billion. 2 million yuan is indeed a huge investment.

Lu Yiming smiled and said, "Forget it, don't think about it so much, the money is earned from selling the land area, and the land is worthless."

With a salable area of ​​4000 square kilometers, people are now selling less than 150 square kilometers, and they can still sell it for a long, long time.

"It's a pie that fell from the sky. Even if you are cheated, it's just a little less money."

"These are the foundations accumulated by other civilizations over the years. It is not too little to learn a little bit."

Of course, the giant tortoise civilization must guarantee the reliability and authenticity of this study, otherwise it will have to pay a certain amount of compensation.

The purchase of this kind of quota is based on research considerations on the one hand. The expert team just wants to find an opportunity to get in touch with this kind of super life form that is friendly to humans.

This kind of supernatural life that is friendly to humans is actually quite rare. So far, I have only encountered a dragon, and this Xuanwu who has not yet met.

Maybe it is possible to discover supernatural elements similar to the Z element?Maybe it is possible to clone a Xuanwu again?

It's not impossible!

People found a strange healing factor in that little tree turtle. The effect of this healing factor is not as good as Z element, but it is also one of the important reasons why it can grow so huge without organ failure and death.

What is the level of wisdom of Xuanwu?Does it also have similar special elements in its body?

These are all places to visit!

On the other hand, some people think that if Xuanwu is really able to communicate, it might be beneficial to bring his super life form there and study for a while.

For example, the little golden dragon and the eight dragons might be able to learn something!

The little golden dragon and the eight dragons were all born with the luck of the Sea of ​​Clouds. They were all prosperous and all were damaged. It was impossible for them to be abducted.

Although they have some natural abilities, they play and play in the reservoir every day, eating and basking in the sun. Although they have started training spiders and tree turtles now, they still have too much free time. It is not a waste of their talents. what a good thing.

So under such circumstances, the two parties hit it off, and each signed a cooperation agreement with their own thoughts.

Lu Yiming took a deep breath, he was in a good mood, and a big deal was completed like this!

The Giant Turtle Empire is the second country other than the Great Jin Empire to join the Cloud Sea Alliance without any conflicts.

Therefore, their strength is best preserved, they occupy a lot of land, and their population is also the country with the largest population except the capital of the sea of ​​clouds.

Moreover, they are also the most modern countries, having advanced their technology to the age of steam represented by the first industrial revolution.

They have trained many craftsmen and have a group of professional industrial talents.

As for the other civilizations, there have been more or less conflicts and conflicts, and they are honest after being beaten up, and their national strength is not comparable to that of the Giant Turtle Country.They were all very nervous about the arrival of the Giant Turtle Nation.

"No wonder the Great Jin Kingdom is a bit hostile to them..." After Lu Yiming realized this, he also understood the competitive relationship between these countries.

In the next half month, the multi-national joint army formed by the Yunhai Alliance inspected the internal ships of the Giant Turtle Civilization in detail, and after confirming that there was no abnormal risk brought by the evil gods, the fleet finally entered the planet slowly. Became a member of the Cloud Sea Alliance.

During the inspection process, Lu Yiming finally saw the legendary psychic beast - "Xuanwu".

Unexpectedly, its size is not too large. Compared with the real giant tortoise outside, it is really much smaller.

It's the size of a car and has a room of its own.

Even the newly born giant tortoise is bigger than the white tortoise in front of him.

But it looks very beautiful, the whole body is like white jade, and the surface of its tortoise shell has complex natural patterns, as if the truth of the universe is written on it, making people addicted to it at a glance.This is a positive spiritual force field that makes people feel peaceful and comfortable.

After hearing the sound of footsteps, it slowly poked its head out of the turtle shell.

"Captain Lu, this guy's mental strength is at least 80! Good guy! This big turtle is not simple, but it does not have any malicious intentions, it is just very curious about us."

The usual evil gods, in the eyes of emotional observers, have a strong atmosphere of emotional pollution.

This white turtle is completely different, that is to say, it has never engaged in demagoguery, nor has it ever eaten people.

Lu Yiming's heart moved, he made a bow, and said, "Hello, Your Excellency Xuanwu. It's a pleasure to meet you."

"According to our agreement with Giant Turtle Country, in the future, there will be about a hundred students studying with you for a year. I will trouble you then."

The black eyes of the old white tortoise scanned everyone, and an old voice sounded in their hearts: "Dear technological civilization, hello, I will abide by the promise of the giant tortoise."

"One hundred students, as long as they are brought to me, I am willing to teach them."

It paused for a while, and then asked: "Visitors of technological civilization, I have a big question to ask you: Is there ultimate truth in the world?"

Lu Yiming was stunned for a moment, what is the problem.

Is the turtle a philosopher, or a physicist?

He gestured with his eyes, but did not answer the question himself.Instead, an expert who followed said: "We haven't found the ultimate truth. But we may have found a part of the relative truth..."

He flipped through some e-books in his laptop, "This is a mathematics textbook. If the ultimate truth exists, then we believe that it can be summarized by mathematics with a high probability. Everything in my world can mostly be found with a corresponding mathematical model." , if we can’t find it, we can only think that our ability is not enough.”

He found another book: "This is a physics textbook. We believe that modern physics can approach the truth. Although physics is not as good as mathematics and can only approach the truth, it is also a top-notch subject."

After all, that's what the chain of academic contempt is all about.Mathematics despises physics, and physics despises other subjects, especially chemistry and biology, which are at the bottom of the chain of contempt.Most of the theories used in these two disciplines are approximate theories, that is, things that are clearly wrong can be explained very well.

If a person with obsessive-compulsive disorder takes these two courses, he will feel crazy.

"You see, this is the model we have found, the closest to the truth! We named it the 'Standard Model', which can explain most of the physical phenomena. But it is only most of it, and there is a small part that cannot be theoretically explanation, so it's not perfect."

He dug out the photos about the standard model, and when the huge Lagrangian was displayed in front of Xuanwu, Xuanwu showed unprecedented bewilderment.

What are these ghost symbols? This old turtle can't understand them at all!

But they are so beautiful, as if they contain the avenue of truth... For no reason, Lao Gui felt a sense of beauty in his heart.

Chapter 617 What is truth?

As a truth-seeking tortoise, when I see these ghostly symbols, I seem to have a voice shouting loudly in my mind: that's them!That's it!

Cosmic truth!The truth of the universe is before your eyes.

The white tortoise "Xuanwu" was born in an extremely remote age. Most of the time in its life, it was in a daze, just like an ordinary tortoise, eating, drinking, and sleeping in the sun.

In Yanghe, after living for a long time, there will always be some miracles.

Due to some unknown reasons, "Xuanwu" gave birth to his own wisdom in a ignorant manner.

The tortoise shell on its body grows mysterious and complicated mysterious pictures and texts.With the help of these pictures and texts, it mastered weak supernatural power and survived in the chaotic environment.

It began to travel around the world, traversing all parallel universes on the Yang River.

Most of the world is full of broken mountains and rivers, and there is not even a living person.

But there are also small parts of the world where humans survive completely.

Until one day, it came near an ancient civilization.

That is really a strange country, it is obviously very weak, but it seems to be loved by heaven and earth, and it has not been invaded by disasters.

In this small island country, many mathematicians, philosophers and private individuals were born.

Xuanwu lived in that country for 20 years, and because he was so beautiful, he was raised as a divine beast.The person responsible for teaching it was a great sage. Under the earnest guidance of this sage, Xuanwu learned the existence of truth for the first time.

"Truth is the way the world works!"

"The operating rules of the world are the truth!"

"How can there be any gods in this world! Even if there are, gods will die! Only the truth will last forever!"

Unfortunately, a disaster broke out, and the weak country was invaded by a powerful enemy.

At that time, Xuanwu was just a little turtle, unable to prevent the destruction of the world. Although it gave birth to preliminary wisdom, it was only preliminary and ignorant.

And when the enemy was overwhelming and life was counting down, the sage was sitting beside the incomplete stone wall, drawing a geometric figure on the sand.A monster approached, and with a haughty gesture he said, "Go away and leave my truth alone!"

The monster didn't know the truth about human beings, so it frantically pounced forward and killed the ancient sage.

This scene will never be forgotten by Xuanwu.

It is not only the death of the sage with emotion.

Everyone will die one day, the world is shattered, and the sage is ready to die.

Even its Xuanwu will eventually die one day.

What it is most touching is the determination of the sage to pursue the truth before his death...

Truth, truth, how many people have been fighting for it, just wanting to get the ultimate truth!

So Xuanwu once again started the process of traveling the world.

This question has been asked by many civilizations in the long past.Because the appearance is almost perfect, it can be regarded as a divine beast every time, and is enshrined by major civilizations.

"What is truth?" Xuanwu would ask them this question.

Some start from the experience level, and some people think that truth is "cow".

The cow is the incarnation of the gods. As long as you understand everything about the cow, including cow dung and cow urine, you can grasp the true meaning of the truth.Drink some cow urine when you're sick, and the cow will tell you all the truth.

There are answers from the philosophical level, the inexplicable sophistry of "truth is born after a hundred question marks" is very unsatisfactory.

There is also an elaboration on art: "In art is truth. Because art is the embodiment of human spirit, it is the perception and understanding of the existence of transcendence. Therefore, what is really displayed in works of art is not a mere object. The real world made up of content, but human emotions.”

"Without the existence of man, the existence of the world has no meaning."

All in all, these answers are not satisfactory!

As for the answer of the giant tortoise civilization, "I don't know."

This answer is also very common. If you don't know, you don't know. Xuanwu is not so easy to fool.

However, at this moment, it heard an unprecedented hardcore answer!

"Math and Physics!"

Xuanwu is not so easy to fool, its inherent spiritual sense has allowed it to see through a large number of liars, and it is not just a random ghost drawing, which can make it satisfied.

However, there are a large number of top scientists in front of it. After hundreds of years of exploration, no matter how it perceives it, it thinks this is a sincere answer!

Moreover, influenced by the first sage from the bottom of his heart, Xuanwu also likes mathematics and worships mathematical theorems.

Mathematics is based on logical speculation. What is true cannot be false, and what is false cannot be true. Everyone can study it, and everyone can make achievements.

It doesn't lie!

"This answer is very good, respected technological civilization, it seems that you have already identified this path."

"I also sincerely hope that this road is smooth..."

The old turtle opened his mouth and seemed to laugh, "I have another request here, can you give me a copy of your civilization knowledge? I also like mathematics knowledge very much, but it's a pity that the mathematics knowledge of the giant tortoise civilization There are too few books, looking around, it’s not enough to read.”

When this question was asked, Xuanwu seemed a little nervous.

It has no other hobbies in this life, but likes to count numbers and divination.

Its life cycle is too long, it has witnessed the prosperity and decline of countless civilizations, and it is used to life and death.

A child, when he wakes up, grows up and reproduces the next generation; when he wakes up again, the former youth is already old.Looking back on the past, he realized that time had passed and he had accomplished nothing, so he told Xuanwu about his life experience.

Love and hatred, ups and downs, other people's feelings, like a person drinking water, knowing whether he is warm or not.

Therefore, it looks quite indifferent to the warmth and coldness of the world, and it will naturally become indifferent when it has more knowledge.Humans are an intelligent species, but their lifespan is too short, and many people are pursuing some boring pursuits.

But mathematics is different, right is right, wrong is wrong, and it can be pondered for a long time.Every step forward on this path is equivalent to eternal progress.

Lu Yiming seemed a little nervous. Among them, there were no mathematicians.

Talking about the mathematical laws he invented, Xuanwu became babbled unexpectedly: "Old Gui, I invented the method of tortoise shell divination, a large part of which is the use of mathematical principles: sixteen squares!"

Xuanwu spat out a jet of water, drew a sixteen-square grid on the ground, and filled it with sixteen numbers from 1-16. Every horizontal line, every vertical line, and the numbers on the diagonal line are all equal.

"Above the sixteen squares, there are 25 squares, 36 squares, and 49 squares. It seems that they can be endless, so keep counting! But the ninety-nine and 81 squares can't be made up. No one It can be discussed, what a pity!"

Lao Gui is very proud of his mathematical invention.

After all, it usually stays in this small room, and no one talks to it. As for the documents of the Giant Turtle Kingdom... it has been lost in previous disasters.
